Title: Method of selecting quantizer values in video compression systems
Inventor: SINGH KISMAT
IPC: H04N7/26
Filed: 2006-12-21
Abstract: A method of obtaining a quantization value for macro blocks of a picture for video compression includes estimating (11), for a plurality of quantization values, a size of the picture in terms of a sum of all quantized coded coefficients. A linear relationship between a size of a macro block and activity of the macro blocks is assumed (12), where the activity of the macro block is the number of coded coefficients in the macro block before discarding any coefficients or quantizing the remaining coefficients. The macro blocks are divided (13) into groups by their activity level such that substantially the same number of pre-quantization coefficients are in each group. An average activity of each group is determined (14). A quantization value for each group is determined (15) from the assumed linear relationship between a number of bits per macro block and activity of the macro blocks and the average activity of the group, as imposed by a predetermined bit rate.

Title: Tap
Inventor: BELIAEV PAVEL
IPC: F16K27/06
Filed: 2007-02-13
Abstract: A tap comprises a body 110 and a threaded tail pipe 120 having an internal bore through which water may pass and a threaded outer surface 121. On the tail pipe 120 are a locking nut 122, a locking washer 128, a pair of anchor means 123, a washer 124 and a back nut 126. To fit the tap to a surface, the tail pipe 120 is passed through a hole in the surface. The hole is of such a size that the back nut 126 and anchor means 123 can pass through the hole but the locking nut 122 and locking washer 128 are unable to pass through. To secure the tap in position, the locking nut 122 is driven towards the back nut 126. This causes the anchor means 123 to become compressed and deform outwardly thus engaging the edges of the hole and securing the tap 100 in position.

Title: Control of a high speed brushless motor
Inventor: CLOTHIER ANDREW CHARLTON
IPC: H02K21/12
Filed: 2009-04-04
Abstract: A motor system (5, fig.2) comprising a single phase brushless dc motor and its control system are disclosed. The motor is suitable for operation at high speed, for example at speeds above 60,000 revolutions per minute (rpm). It is suitable for use in a vacuum cleaner. The motor includes a single winding (19, fig.3) arranged on a C-shaped core (8, fig.3) which enables a high fill factor to be achieved for the winding. A Hall position sensor is used. In operation, the winding 19 is sequentially excited and freewheeled by a conventional H-bridge drive circuit. It is disclosed that the winding is excited in advance of zero-crossings of the back-emf in the winding by an advance angle, and is freewheeled over a freewheel angle. Both the advance angle and the freewheel angle may be varied in response to changes in the speed of the motor and the excitation voltage. The variation of the advance angle and freewheel angle is stored in the drive controller (16, fig.2) as a power map. Each power map comprises a lookup table storing an advance time and a freewheel time for each of a plurality of voltage levels. Consequently, constant output power is achieved over an operating speed range spanning at least 10,000 rpm, irrespective of changes in excitation voltage, which may come from a battery.

Title: Projection device for producing a virtual image
Inventor: FIESS REINHOLD
IPC: G02B30/25
Filed: 2009-12-01
Abstract: A projection device for producing a virtual image has a first display surface 21 and a second display surface 27 for producing first and second real intermediate images and imaging optics 3 to direct the light of the real intermediate images onto a reflection surface 4 suitable for producing the virtual image. An optical switch-over device 24 enables light to be passed selectively from the first or the second display surface onto the imaging optics 3. The respective optical paths from the first display surface 21 and the second display surface 27 to the imaging optics 3 are different in length, so it is possible to switch between virtual images that are of differing size or apparent distance from the viewer. Switching may be achieved by using polarised light from a light source 20 and retardation (quarter wave) foils 25, 28, the respective states being shown in figures 3 and 4 where optical switch-over device 24 is embodied as a partially transmissive mirror acting as a polarisation beam splitter. The device may be used to provide a head-up display on a vehicle windscreen.

Title: Improved variable-speed gearing particularly for reeling or winding machines for paper and textile webs, threads, ropes and the like
IPC: F16H9/12
Filed: 1934-04-03
Abstract: 424,537. Controlling variable speed gearing ; winding or reeling webs, threads, &c. MARTINY, H., 23, Hohestrasse, Gummersbach, Germany. April 3, 1934, No. 10129. Convention date, April 3, 1933. [Class 80 (ii)] [See also Groups IX and XVI] In a machine for winding or reeling textile or paper webs, threads, ropes, wires, &c., the winding shaft is driven at a speed varying inversely with the diameter of the roll &c., being wound from a shaft forming part of a friction coupling through a continuouslydrivable gear, the driving shaft being driven with a predetermined amount of slip, and, with the other part of the friction coupling, controlling a differential gear which controls the continuously variable gear to maintain the predetermined amount of slip whatever the torque transmitted. The driving pulley 1 carries a plate 2 forming part of the friction coupling and pressed by a spring 7 against a plate 3 keyed to the driving shaft 4 carrying the cone pulleys 17, 18 connected by a belt 42 with the other cone pulleys 19, 20 of the continuously-variable gear on the winding shaft 16. The screwed shaft 27 carries nuts 26 connected to the cone pulleys and is keyed to a hub 29 forming part of a safety coupling, the other member 30 of which carries the planet wheels 33 of the differential gear. The wheels 33 gear with a pinion 34 driven from the pulley 1 and with internal teeth 35 on a casing 36 geared to the shaft 4 and the gearing is so arranged that, for a definite amount of slip between the shaft 4 and pulley 1, the pinion 34 and casing 36 are driven at the same speed in opposite directions, the wheels 33 thus turning on their shafts but not revolving and the shaft 27 remaining stationary. As the diameter of the roll being wound increases, the slip between the shaft 4 and pulley 1 increases, the pinion 34 rotates at a greater speed than the casing 36 and the wheels 33 with the member 30 revolve in the same direction as the pinion 34 thus rotating the hub 29 and the screwed shaft 27 to move the cone pulleys and reduce the speed of the shaft 16 with the restoration of the definite slip between the shaft 4 and pulley 1. The pressure of the spring 7 pressing the plates 2, 3 together is adjustable by a hand-wheel 10 and chain gearing and the coupling is cooled by vanes 14 on the pulley 1 ; the setting of the cone pulleys can be manually adjusted by a wheel 28, and the safety coupling can be dispensed with by fixing the hub 29 to the ring 30 or forming them in one piece. The variable-speed gear is stated to be applicable to the driving of vehicles.
